While the ribs are cooking, make the sauce. In a medium pot, combine the ketchup, Jack Daniels, 3/4 cup brown sugar, garlic, vinegar, Worcestershire, liquid smoke, and the 1 teaspoon salt. Heat over medium-high heat until boiling, stirring constantly. Lower the heat to low and simmer, uncovered, for 30 minutes, stirring occasionally. Set aside, off the heat, when done.
